摘要
合成了结晶程度较高的Co(OH)2,并对其电化学性能进行了研究。充放电实验表明:Co(OH)2具有一定的放电比容量:98.4mAh/g,多次充放电实验表明它的容量较为稳定。循环伏安实验表明:氢氧化钴电极具有一定的可逆性。X射线衍射实验结果说明:电极反应是在CoOOH和Co(OH)2之间进行的。通过对氢氧化钴的电化学性能研究,能进一步了解Co(OH)2作为添加剂的作用机理。
Crystalline Co(OH)2 was synthesized and its electrochemical characters were studied. The chargedischarge experiments show that cobalt hydroxide electrode has a comparatively stable capacity of discharge, which is about 98.4 mAh/g. The experiments of cyclic voltammety show that the cobalt hydroxide electrode is reversible. The result of Xray diffraction shows that the electrode reaction takes place between CoOOH and Co(OH)2. The function of cobalt hydroxide, as an electrode additive, is known more clearly through the studies of its electrochemical properties.
